Integrating Spheres
-
Artifex Engineering GmbH & Co. KG
We offer integrating spheres made from a special polymer suitable for the wavelength range 250nm – 2.5 µm. For longer wavelengths in the range 700nm – 20 µm, a gold coating on a rough, metallic surface is used. Since lasers in this spectral range are usually also high power, we use solid copper as a thermally conductive substrate material. By choosing the size of the integrating sphere, the overall sensitivity of the system can be adjusted. In addition, the detector is independent of inhomogeneities in power density and polarization. The detector is also independent of the incidence location and angle of the laser radiation.

Flame Ionization Detector
-
A flame ionization detector converts a hydrocarbon gas concentration into an electrical signal. The flame is hydrogen fueled and burns in hydrocarbon free combustion air. Either side of the flame are two electrodes between which an electric field is generated by means of a polarization voltage. The sample is pre-mixed with the fuel gas and heated in the flame to a temperature at which the hydrocarbon molecules ‘crack’ and CH fragments appear. These CH fragments are oxidated by the oxygen in the combustion air resulting in the formation of CHO+ ions. The ion current then passes to the electrodes and the resulting current measured is proportional to the quantity of C atoms derived from organic compounds.The Thermo-FID features two separate microprocessor controlled pressure compensations to avoid any influence from environmental or sample conditions. In addition, the complete Thermo-FID range of analyzers are equipped with a flame trap that is used as a heated sample inlet filter. The measurement chamber and all material in contact with the sample gas are heated between 120°C and 200°C to avoid condensation.
